j fyingvapors and gases by t eign matter or heavy particles by the useof wateror other liquid, the air or gas is first 'arraaa'riis r'on Toall whom it may concmf 'which the following is a specification;

In an washers or other aplparatusfor uripassed through a sp'rayorshower,- by-which the heavy particles are preci itated, and then througan eliminating c amber over baifles or plates, b which the moisture andlighter un recipitated matter eliminated. The e ciency of such ap aratusdepends upon the. thoroughness of t e precipitation of the matter by theliquid spray or shower in the purifying chamber, and also upon.thecomplete removal of the moisture in the eliminating chamber. The moreeffective the spray or shower in mingling inti mately with the air orgas, the more moisture will there be carried by the air or as into theeliminator to be'removed -b the allies. 7

EMS one of the objects 0 my invention to V obtaina most thorough actionof the cleans mg liquid in the purifying chamber and a, most efficientelimination of the moisture and unprecipitated matter in the eliminatingchamber.

' The efficiency of the moisture eliminating baflles or plates dependsin a great measure upon the rapidit with which the deposited moisture,is disc arged from them, and a part of my improvements relate to theconstruction and arrangement of" the baffle.

lates whereby the discharge of the moisture is facilitated and thecurrents of air or gas act in aid of gravit in discharging the moistureand keeping t e plates cl'ean.

construction and combinations of parts by which these results areattained.

In, the drawings: Figure 1 is a lan view of one form of my a paratuswith t e casing in longitudinal section to-expose the, interior;

, Fig. 2- is a longitudinal vertical section on the line AA of Fig. 1;-Fig. 3. is .a longitudinal vertical sectionof a different form of thea aratus; Fi 4 is a horizontal section on t e me B..-B 0 Fig. 3; Fig. 5is a transverse vertical section on the line 0-0 of F' 4, and Fig. 6 isa lan view illustrating anot er form of the ba es or eliminator-plates.

0 is the outer shell or casing throu h which passes the air or gas to bepurified. he passage of the air or gas through the apparatus ma beproduced or aided by suitab e means suc as a fan 12. The air or'gasenters the purifying chamber through the open or inlet end of the casingand passes througha shower or spray of water or cleansing liquid. Thisspray or shower may be produced by any suitable means. f I: prefer,however, toemploy spring spray-nozzles c as shown.

The water or li uid is supplied through a series of. nozzles aving theircutlets controlled by conical s ring spray heads (1, which he water infinely divided condition in conical showers. The character of the spraproduced may be regulated by adjusting t e tension of the springs 41 ofthe spray heads by means of valve stems e. s The spray heads may bearranged at'the top or bottom or at the sides of the purifying chamberor both at the top and bottom as shown in Fi 2. In the latter case avery effective and t orough diffusion of the water or cleansin liquid isobtained.

he air inlet of the purifying chamber may be providedwith transverselouvers a for the purpose of preventing the spray from passing outthrough the an: opening in case the fan stops. They also assist indISt-llblltin the .water through. the chamber and enab e a shorterchamber to be employed.

Back of the purifying chamber is the eliminating chamber containing thebaflles or eliminator lates f, which are preferabl upwardly andforwardly inclined towar the inlet, and are arranged in staggeredrelation so that the air or gas must circulate around them in assingrtothe outlet. .As shown int . these-ha as or plates are arranged in stag-Lgered rows, the plates of onerow spanning the space between adiacentplates in the next row. In Figs. 1 an 2 the plates or bafiles are ofchannel shape in cross section, but I do not mean to confine myself toany particular section. In Figs. 3, 4 and 5' they are flat and in Fig. 6they are formed with longitudinal strengthening ribs 9.

his a false bottom or base support for the lower ends of the bafliles f.It extends above the bottom of the casing and forms therewith a space orliquid chamber 'i terminating at the end in a Well 1'. The false bottomIt is provided with slots or openings is adjacent to and in front of thelower ends of the baffles f through which the li uid and extractedmatter deposited on the affles by'the air or gas flows-into the chamber4,. The bottom of the casing is preferably inclined to drain into thebottom of the casin well 7. The front end. of the false bottom it isprovided with a down-turned rib h and adjacent to this is a transverserib a on the These ribs form a water seal between t e spray chamber andthe space i which prevents ,any air passing directly into the s ace '5without entering the eliminating cham er.

m is a valved drain pipe from the well 1' by I which the contents of thewell with deposited matter may be dischar ed. I prefer to use the watersupplied to t e well as the spray water, and for this purpose I haveshown a discharge pi e n provided with a strainer head 0 by w "oh thewater may be drawn from the well and supplied to the spraying heads.

is a supply pipe having a float controlled by which hquid may besupplied to form a tubular eliminating chamber with the liquid chamberor dead space 03 between the casing and the outside of the cylindricalsections. Each section consists of an outer ring having thebaflies'extending from the lower rear edge to the upper front edge andthe opening 7c in the lower portion of the rin in front of the lowerends of the baffles. he rings are of smaller diameter than the casing a,and are sup orted eccentrically by means of supporting ugs s,.so thatthe space '1', is

- formed between the casing and the ringsec- 5 let of the apparatus'a'ndpasses through the tions. The position of the baflies in successivesections are reversed as shown so as to produce the staggered effect.This may be accomplished by arranging the baflies out of center andreversin successive rings.

The air or gas to e purified enters the insssuse shower or s ray in the'spray chamber, and

v the dust an heavier particles of matter are removed by the spray andprecipitated. The air then passes through the eliminator chamber and asit moves over the baffles or eliminator lates it deposits the moisture,

with such lghter particles of matter as it still contains, upon thefront surfaces of the plates, and finally passes out purified andposited moisture is discharged. The inclination of the plates or bafflesdownwardly and backwardly with reference to the direction of movement ofthe air or gas aids materially in discharging the moisture, since theair currents impin mg on these inclined surfaces are more or essdeflected and this defiection tends to produce a downward pressure onthe moisture, acting in aid of gravity to drive it to the outlets.

By discharging the moisture into a dead space or chamber 1' sealed tothe entrance of air from the spraying chamber I avoid any tendency ofair currents passing over the body of discharged water to take upmoisture from it and again deposit such moisture on the eliminatorplates without any useful result. Thereis also a tendency to theproduction of a lower pressure in the chamber i and the creation ofdraft downward through the opening is which facilitates the discharge ofthe moisture from the plates. The efl'ective removal of the moisturefrom the plates also removes such articles of matter as have beendeposited and tends to keep the plates more clean and eflicient.

While I have shown my improvements in a form particularly ada ted forair washing or purifying by means of water, I do not mean to limitmyself to this use, as the apparatus may be applied to other uses, such,for example, as a smoke condenser for removing the unconsumed carbonparticles of smoke, and particularly of smoke produced by the combustionof soft coal. The apparatus may also be used with cleaning fiuu s otherthan water.
